1 Introduction to Information Retrieval
Got a question concerning literature? Ask! Marion Bierhahn (4630) Where is the library? Bldg:1d Rm:EG.440 Opening hours: Mon – Thu: 9:00 – 16:00 Fri: 9:00 – 14:00

2 Access to the Library The library is open for everyone.
Outside opening hours access with DACHS-card With DESY-account @ Bldg.6, Rm.110 To borrow books library-card @ Library (Bldg.1d) Marion Bierhahn

3 Library Collection Books
ALEPH books-catalog from home-page ( Conference proceedings Preprints, reports, thesis Journals incl. Science, Physics Today, … Daily international Newspapers

4 Electronic Resources arXiv.org For research articles
Database of metadata for HEP search for articles Preprint repository, stores full-text Some search functionality arXiv.org Similar to INSPIRE, for Astrophysics ISI Web of Knowledge for published articles Thomson Reuters SCOPUS for published articles Elsevier

5 INSPIRES History 1963: HEPindex by DESY (book of publication references) 1974: SPIRES-HEP SLAC in collaboration with DESY Mid 80’s: remote access of SPIRES via more databases: CONF, EXP, INST, HEPnames, JOBS Fermilab joined Mar. 89: Information Management: a proposal -> WorldWideWeb Dec. 91: first web-server outside of Europe close collaboration with arXiv Nov. 2011: INSPIRE replaced SPIRES collaboration of CERN, DESY, Fermilab, SLAC Apr. 2012: SPIRES front-end shut-off

6 INSPIRE Search HEP: (16.7.) 1 009 193 records
Powerfull search syntax or google-style Use HELP

7 4* Search Syntax INSPIRE
Google: Aad Higgs photon searches everywhere in metadata SPIRES: fin a aad, g and t higgs and k photon use stop-words to structure search INSPIRE: author:”aad, g*” title:higgs keyword:photon use blank to separate search terms, needs quotes MARC: 100__a:”aad, g*” 245__a:’higgs’ 6531_a:/photon/ /search text/: substring, regular expressions possible ‘search string’: substring – may take very long “search sting”: full string Don’t mix SPIRES with other syntax

8 Author profile Ongoing: cleanup of profiles author person

9 SCOPUS DESY has test subscription. Build your own search query from pull-down. Use Help

10 SCOPUS

11 Web of Science DESY has subscription. Build your own search query from pull-down. Watch the syntax! Esp. for authors.
